Recent projects have required NTH to provide site-civil engineering, subsurface utility engineering (SUE) locating services, pipeline routing design, base mapping, geotechnical engineering, materials testing, stormwater pollution prevention planning, construction administration, municipal permitting, and environmental agency permitting.
NTH is also called upon to manage work by its sub-consultants for topographic and site features surveys, easement documents, construction staking surveys, and due diligence and permitting for ecological and cultural resources. Reasons for NTH’s increase in this line of business include are an increase in the use of natural gas (over coal), organized programs for replacement of aging gas distribution pipe networks, NTH’s growing expertise in this industry, and a robust economy.
